A storm bringing high winds and heavy rain was sweeping through the North East of the US, while wild winter weather elsewhere brought tornadoes and deadly accidents in the Midwest and South, flood threats in Florida and blizzards in the Northwest.

New Jersey governor Phil Murphy declared a state of emergency and New York City officials evacuated nearly 2,000 migrants housed at a sprawling tent complex ahead of predicted wind speeds that could top 70mph (112kph) at times.

In Maine, Governor Janet Mills delayed the opening of all state offices until noon Wednesday due to the storm.

The National Weather Service warned of possible major flooding in portions of Long Island with up to nine-foot seas through Wednesday morning and a chance of major and minor flooding along streams and rivers throughout the Tri-State area, even though rain was expected to tail off.

The wild weather came as portions of the Northeast were still digging out from a nor’easter that dumped more than a foot of snow in some areas over the weekend.

On Tuesday, the same weather system brought heavy rain, hail and at least three reported tornadoes to the South before moving eastward.

Rain and high winds extended into the nation’s capital, forcing Vice President Kamala Harris’ aircraft to divert from Joint Base Andrews to Dulles International Airport near Washington when it encountered wind shear, a sudden shift in wind direction or speed.

Near Cottonwood, Alabama, a small city near the Georgia and Florida borders, 81-year-old Charlotte Paschal was killed when her mobile home was tossed from its foundation, the Houston County coroner said.

A suspected tornado had touched down in the area.

Police in Clayton County, south of Atlanta, said a man died during heavy rain when a tree fell on his car on a state road in Jonesboro.

More than 80 public school systems across Georgia called off classes entirely while others taught students online or delayed the start of in-person classes.

In North Carolina, one person died and two others were in critical condition after a suspected tornado struck a mobile home park in the town of Claremont, north of Charlotte, said Amy McCauley, a spokesperson for Catawba County.

A possible tornado knocked down several old brick storefronts in downtown Bamberg, South Carolina, blocking the main intersection through the city about 60 miles south of Columbia.

Thousands of bricks blocked US 301, the main road through that part of the state, and about 40 homes and businesses were damaged or destroyed, said Democratic Rep. Justin Bamberg, who represents the area.

Storm-related injuries were reported in Florida, but no deaths.

A section of Panama City Beach showed parts of roofs blown away, furniture, fences and debris strewn about, and a house that appeared tilted on its side, leaning on another home.

The National Weather Service office in Tallahassee planned to send out three tornado survey teams on Wednesday to examine suspected tornado damage in Walton, Bay and Jackson counties in Florida, and two more on Thursday to look at Houston County, Alabama, and Calhoun County, Georgia.

Many areas of Florida remained under flood watches, warnings and advisories early Wednesday morning amid concerns that streams and rivers were topping their banks.

Governor Ron DeSantis, who gave his State of the State address as tornado warnings were active outside the Capitol, issued an executive order to include 49 counties in North Florida under a state of emergency.

Another storm that began on Monday buried cities across the Midwest in snow, stranding people on roads.

Some areas saw up to a foot of snow on Monday, including Kansas, eastern Nebraska and South Dakota, western Iowa, and southwestern Minnesota.

In southeastern Wisconsin, an SUV driver died Tuesday in a head-on collision with a semitrailer on a slushy, snowy state highway, authorities said.

In western Michigan, a 35-year-old woman died after she lost control of her minivan on a slushy road and it collided with an SUV, the Lake County Sheriff’s Office said.

The ambulance taking her to a Grand Rapids hospital, where she was pronounced dead, was struck by another vehicle en route there, and a second ambulance was needed to finish the transport to the hospital.

The weather has already affected campaigning for Iowa’s January 15 precinct caucuses, where the snow is expected to be followed by frigid temperatures that could drift below zero degrees (-18C).
